The mighty Nepalese Himalayas are the highest mountains on earth. This is no protection for their glaciers, which are receding rapidly due to climate change. The forests that cloak the foothills, have been badly deforested, cut down to provide fuel for local people. The rivers in Kathmandu are some of the most polluted in the world. All this will lead to serious water shortages downstream in future years. Despite all its problems this poor country remains one of the most stunningly beautiful places on earth, whose peoples are both friendly and welcoming.
